16. MEASURING ECO-EFFICIENCY OF PRODUCTION IN OECD MEMBER COUNTRIES : A STOCHASTIC FRONTIER ANALYSIS
Master-uppsats, Umeå universitet/NationalekonomiSammanfattning : This paper analyzed the eco-efficiency of 27 OECD member countries by using output-oriented Stochastic Frontier Analysis (SFA) model. In the set-up of the model, Gross Domestic Product (GDP) was used as a good output whereas Carbon dioxide (CO2), Sulphur dioxide (SO2) and Nitrogen oxide (NOx) emissions were used as bad outputs.

17. Controls of the partitioning of nitrate between DNRA and denitrifiers
Master-uppsats, SLU/Dept. of Forest Mycology and Plant PathologySammanfattning : In arable soils, the importance of denitrification, a respiratory process where nitrate (NO3-) is stepwisely reduced to nitrogen gas and nitrous oxide (N2O) is well established. More recently has dissimilatory nitrate reduction to ammonium (DNRA) gained interest as its importance in agricultural soils might have been largely overlooked. LÄS MER
18. Investigation into Urea Deposit Risk by varying parameters in the control system related to urea evaporation
Master-uppsats, KTH/KemiteknikSammanfattning : I och med nuvarande och kommande lagkrav för utsläpp från tunga lastbilar finns en efterfrågan på utvecklade strategier för utsläppsminskning. För att kontrollera utsläppen av kväveoxider (NOx) används katalytisk omvandling med AdBlue (vätskeblandning av urea och vatten). LÄS MER
19. Preliminary experimental study on the affect of water of the hydrogen reduced hematite pellet
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Global warming is one of the most important challenges that we are facing today. Since carbon dioxide (CO2) is by far our most common green house gas pollutant, most large corporations need to reconsider how their production is performed to keep the global warming below 2 ◦C.

20. Modeling and optimisation of a rotary kiln reactor for the processing of battery materials
Master-uppsats, KTH/KemiteknikSammanfattning : Roterugnar är cylindriska kärl som används för att höja materials temperaturer i en kontinuerlig process som kallas för kalcinering. Roterugnar kan tillämpas i olika processer såsom reduktion av oxidmalm samt återvinning av farligt avfall. LÄS MER
